摘要： Block noises at block boundaries are removed, but when a contour line in the original image matches a block boundary, the degree of block noise removal is adjusted and image quality is improved. An adaptive filter has a step of calculating the weight of pixels near the block boundary by a high-pass filter, and a step of determining an adjusted value for the pixels near the block boundary based on the weight. The pixel values near the block boundary are adjusted and block noises are removed. A low-pass filter is applied to pixels near the block boundary to determine a filtered value. The adjusted values of the pixels near the block boundary are determined by obtaining a weighted sum of the original pixel value and the filtered value. Because the high-pass filter recognizes the definition of pixels near the block boundary, and the low-pass filter reduces the difference between pixels near the block boundary, the adaptive filter outputs the adjusted value, and this value removes block noise while retaining image definition.

摘要： Image ringing noise is reduced by calculating a line spread function value of each pixel's luminance in an input image, dividing the input image into a plurality of blocks, and calculating an average value and a maximum value of the line spread function values for all pixels in each block. Based on the average value and the maximum value of the line spread function values of each block, whether a block is an interfered flat block or a non-interfered block is determined and the pixels in the interfered flat block are set as noisy pixels. Whether each pixel in the non-interfered block is an edge pixel or a non-edge pixel is determined and the non-edge pixels in the non-interfered block are set as noisy pixels. The noisy pixels thus set are smoothed, and the smoothed pixels are combined with the edge pixels for output as an output image.

摘要： The invention provides an eyewear device for transmitting a signal and a communication method thereof. The eyewear device comprises a receiving unit, a shutter and a transmitting unit. For example, the receiving unit is capable of receiving a synchronization signal, and the shutter performs an operation in response to the synchronization signal. Meanwhile, the transmitting unit transmits the synchronization signal to another eyewear device. By this way, each eyewear device is capable of receiving the synchronization signal, and re-transmits the synchronization signal to another eyewear device.
